MB4 Mule Block

MB-4 is used with No. 5003-A Center Take-Off Live End Pulley. Mule Blocks are a means of allowing lines to pass over the edge of a sill without rubbing or binding. Dimensions: 6-1/2” long x 6” wide x 2-1/2” high. 

Weight: 1 - 3 lbs. 


Adding turns of any degree to operating lines increases the overall load of the system. Allowance must be made for this additional loading when machines are used to operate the systems. The use of pulleys with wheels larger than those used in the MB series will lessen the effect of the added load.
